Design and Simulation of Tandem Fixed-wing Unmanned Aerial Systems

This paper focuses on the 3D model construction of a tandem-stage fixed-wing UAV and its kinematic simulation analysis. Through an in-depth understanding of the flight principle of a tandem-stage fixed-wing UAV, the equations of motion of this type of UAV are first constructed. Then the flight process of the UAV is exhaustively simulated and analysed using advanced kinematic analysis software. Under the set initial conditions, the dynamic relationship between the lift force and the flight speed and flight time of the UAV during the flight process was obtained, and the relationship between the thrust paddle centre-of-mass angular velocity amplitude, angular acceleration amplitude and the flight time was also explored, and the rule of change between the flight speed, lift force and flight time of the UAV was further analysed.The concluding data from these simulation analyses not only provide an important reference basis for the design optimisation of the tandem fixed-wing UAV, but also lay a solid theoretical foundation for subsequent experimental verification and practical application.
